Diffusers

Control valves are often used to reduce the pressure in the gas or steam networks, which can lead to considerable levels of noise generation, up to 160 dBa. Strategically positioned diffuser will reduce the generated noise to acceptable levels bringing the system in compliance with Australian Occupational Noise National Standard. Noise attenuating diffusers require no maintenance and provide a cost effective solution to excessively generated noise. The system installation life span will be improved considerably as a result of minimising internal vibrations and changing harmful low frequency noise.

Design, fabrication, inspection, testing, and certification of diffusers are in accordance with international requirements of ASME VIII Division 1 or EC Pressure Equipment Directive PED 97/23/EC.
